_DONTWAIT is used with the SHELL statement in QB64 to specify that the program shouldn't wait until the external command/program is finished (which it otherwise does by default).
Syntax
- SHELL [[[_DONTWAIT]]] [commandLine$]
Description
- Runs the command/program specified in commandline$ and lets the calling program continue at the same time in its current screen format.
- Especially useful when CMD /C or START is used in a SHELL command line to run another program.
- QB64 automatically uses CMD /C or COMMAND /C when using SHELL.
- QB64 program screens will not get distorted or minimized like QBasic fullscreen modes would.
Examples
SHELL _DONTWAIT "notepad " + filename$ FOR x = 1 TO 5 _LIMIT 1 PRINT x NEXT |
